DD is 10 and has been pitching for a year and a half. She had been taught HE until I discovered DFP. We began the switch to IR in November. Toward the end of February she began having pain. She has pain only at the location of my thumb in the picture. It is not superficial pain, I have to push my thumb in to reach the area. We have rested and stretched her arm for 3 weeks and today was our first day back. We threw 15 from 9 o'clock, 15 from 12 o'clock, and 15 walk throughs. By the end of the walk throughs, she said she was starting to get tightness in that same area and we shut it down. Is there anything in her mechanics that you guys see that could be the source of her pain?
